The female cur- 

 Ho (Fig. 191,1,) ex- 

 cavates a small cavity in the grape (Fig. 192a), and then 

 deposits therein a single egg of a bright yellow color. The 

 grub (Fig. 1916) which hatches from this egg feeds upon the 

 pulp or tlesh of the grape, and rarely upon the seeds. When 

 fully grown (Fig. 1926) it is about two 

 lines long, and each segment of its 

 body bears on each side a large fleshy 

 tubercle.
